From: Volcanic trigger of ocean deoxygenation during Cordilleran ice sheet retreat
a, CaCO3 content19,28. b, Sediment Sr/Al ratio. c, Counts of coccolith per field of view19. d, TOC content28. e, Opal content28. f, Bulk sediment δ15N, corrected for terrestrial organic matter input28. g, Sediment Ba/Al ratio. The y-axis scales are different between the intermediate-depth and abyssal sites. h, Abundances of productivity-related benthic foraminifera species Islandiella norcrossi from the intermediate-depth site and Elphidium batialis from the abyssal site12,23. The colour legends in a–h are the same
